Defending Bathurst champion Chaz Mostert has been taken to hospital with a suspected broken leg after a terrifying accident in qualifying at the Bathurst 1000.

Mostert was on his first lap in the 40-minute session when he glanced the wall at 16, crashed into 17 and rode the wall leading into 18, the Dipper.

Mostert was assisted from his car by paramedics and taken to the medical centre by ambulance.

The balance of today scheduled events were cancelled and no further action on track today.

Event Chief Medical Officer Kaaren Vinns has given more insight into today's unfortunate qualfying incident at the Bathurst 1000.

"Chaz Mostert has has been taken to hospital in Orange for assessment, he has a leg and arm injury and is in a stable condition," Vinns said.

The five marshals who were invovled in the incident did not suffer from any critical injuries, with four receiving minor injuries and one treated for injuries from flying debris.

However all are receiving the best treatment from medical crews.

"The five marshals who were stationed at the flag point received minor injuries, with one being sent to Bathurst Hospital for further treatment and is in a stable condition."

CAMS will provide further updates on the condition of marshalls if any further news comes to hand.

We ask that all members do not use unofficial social media representatives of V8 Supercars or CAMS as a source for information on this situation.

CAMS thanks all officials, medical staff, emergency services and other volunteers for their professional response to this unfortunate incident.

Chas was talking all through the ordeal and even cracked jokes. “Thank God we signed that contract a couple of months ago!”

Those were Chaz Mostert’s first words to Prodrive Racing Australia team boss Tim Edwards as he lay in the Mount Panorama medical centre this afternoon with a fractured left femur and wrist.

While Mostert was able to joke about the violent accident that ruled him out of the Supercheap Auto Bathurst 1000, wrecked his $500,000 Pepsi-Max Ford Falcon FG X and ended his championship chances, Edwards stressed his young charger was also incredibly upset for his team about the accident.

“He is in good spirits, but I think there is a bit of green stick (pain killing drugs) in that,” said Edwards.

“He is thinking of the team and very apologetic to the boys who put in all the hard work to get him out on the track.”

“But it was good he was able to joke and I am happy to let everyone know about it.”

Mostert was referring to the rich deal he signed earlier this year to extend his contract with PRA until the end of the decade.

Mostert earned that new deal on the back of his massive performances this year, which have included 10 pole positions and five race wins.
